OKI Microline 491 - printer - monochrome - dot-matrix

Whether you need regular output of continuous multi-part forms, fine business correspondence - or combinations of both - 24-pin OKI ML490/491 printers are the single solution. They handle the printing needs of the most demanding environments - including point-of-sale, automation and utility applications such as wholesale or retail sales counters, financial departments, and manufacturing or warehouse sites. Yet they also produce letter-quality type and high-resolution graphics for the office and executive suite.
The ML490/491 sport features that give them a strong edge over their predecessors as well as the competition. An internal cooling fan provides continuous airflow for the printhead - maximizing throughput productivity for long, unattended print jobs. Additional feed rollers provide precise forms handling and printed-character placement accuracy. 3-piece top cover provides easy access and unsurpassed break resistance. The ML490/491 printers run the gamut of paper types and envelopes at lightning speed - reaching 475 cps in Utility/Draft mode and 105 cps in Letter-quality. Their rugged printhead (200 million-character average life expectancy) is made up of powerful samarium magnets and stored-energy pins that deliver precise, sharp characters all the way through to the last page of a 5-part form. The patented OKI closed-loop feedback system assures character placement accuracy. And a zero-tear feature accurately positions continuous forms for a clean tear at the perforation to eliminate wasted stock.
